HUB.

SPECIFICATION forming part of Letters Patent No. 360,858, dated April12, 1887. v

Application filed November 11,1886. Serial No.218,513. (No model.)

To all whom, vit may concern.:

Be it known that I, J AMES REAGIN GRAvENs, a citizen of theUnitedStates,residing at Ringgold, in the county of Catoosa and State ofGeorgia, have 'invented certain new and useful Improvements in Hubs; andI do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to whichitappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specication.

My invention relates to improvements in hubs for carriage and wagonwheels; and it consists in the construction, combination, andarrangement of the several parts, as will be hereinafter described andclaimed.

In the accompanying drawings, Figure 1 is an elevation of my improvedhub. Fig. 2 is a longitudinal section of the saine. Fig. 3 is a detailView 0i' the spoke-holding disk; and Fig. 4 is a detail perspective Viewof the end of one of the spokes.

Referring to the drawings by letter, A indicates the spindle or end ofthe axle, andB the body ot" the hub. The body B of the hub is providedwith a disk, C, which may be cast with and form an integral part of thebody, as shown in Figs. 1 and 2, or it may be made separately, as shownin Fig. 3 and indicated by dotted lines, Fig. 2, and secured upon thebody. The outer face of this disk C is concaved or inclined inwardtoward the center, and is provided with a series of radial ribs,D,corresponding in number to the spokes E. It will be seen by referring tothe drawings that the body B is a straight collarrtted on the spindle A,the inner end of which is of a diameter about equal to the diameter ofthe disk C, and the rest being of a lesser diameter.

The spokes E are held between the disk C and a fiat-faced collar or nut,F, which is screwed up against the spokes over the body B, as shown mostclearly in Fig. 2. .The ends of the spokes E have their wider sidesinclined toward each other to allow of placing the spokes close aroundthe hub, as will be underi .the body B ot' the hub, and a` nut, H,secured thereon, holds the hub in position. This nut H has an outerdiameter equal to the diameter of the body B and an inner diameter equalto the diameter of the end of the spindle A. The top of this nut H isclosed, thereby preventing the access of dirt to the spindle.

I I are slots or notches in the nut H and collar F, which allow of theapplication of a wrench in removing and replacing the same.

J is an opening th rough the body B, by means of which oil is passed tothe spindle to lubricate the same.

My device is simple in construction, and, being composed of few parts,can be inanufactured at a slight cost. The ribs D on the disk O engagethe notches G in the end of the spokes E, and thereby hold them inplace.

Having thus described myinvention.what I claim, and desire to secure byLetters Patent,

The combination, with the shouldered hub B, of the concave-faced disk C,having radial ribs D, the spokes E, having beveled ends provided withgrooves G, and the internally screw-threaded nut vF, fitting upon theexternally screw-threaded end of the hub, substantially as shown anddescribed.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES REAGIN ORAVENS.
